centered around the 2010 death of a SeaWorld killer whale trainer, this documentary is a sharp reminder of our amazing hubris -- especially in the face of nature.
there's a great moment where former trainers acknowledge their naiveté, realizing any bonds they had with the orcas were superficial. a highly intelligent animal, performing dumb parlor tricks for snacks? that was out of boredom and hunger in captivity, and only arrogance would make one assume otherwise.
you can point the finger at the big bad corporation (and SeaWorld gets plenty of screen time as a target), but the blame extends to everyone. "can" and "should" are two different things. the exploitation of killer whales is what happens when we confuse the terms.
